GAS R WATER SWITCH.

SPECIFICATION forming part of Letters Patent No. 573,403, dated December15, 1896.

VApplication filed May 18,1896.

T0 all whom, t may concern,.-

Be it known that I, SAMUEL WEBB GARRI- sON, of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania., have invented certainnew and useful Improvements in Gas or Water Switches; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

This invention pertains to a gas and Water switch; and the objectthereof is to provide an improved switch and switch-box for gas j andwater mains.

The invention consists in the novel features of construction hereinafterfully described and claimed, and illustrated `by the accompanyingdrawings, in whichm Figure l is a vertical sectional view of theswitch-box in operative position. Fig. 2 is a similar View with thebox-cover removed and the wrench in position for adjusting the mainvalve. Fig. 3 is an inverted perspective view of the switch-box cover.Fig. 4 is a perspective view of the wrench.

A designates the box or casing, which projects downward from the surfaceof the pave ment, and a short distance below its upper end are theopposite inwardly-projecting arms B, supporting the circular bearing C.Anguiar rod D extends downward through this bearing and at a pointadjacent its upper end -is provided with the annular shoulder E,

adapted to rest upon the bearing C, and thus support the rod inposition. The upper eX trexnity D of the rod forms a key-ho1d.4 rlhelower portion of the angular rod takes in the angular tubing F, and thelatter is flattened at its lower end to form an oblong depression,whereby the tubular stem is adapted to iit over the key-hold of the mainvalve, as will' be understood. Rod D will turn the tubular stemregardless of its position therein, so that the switch is adapted foroperating main valves at varied depths below the pavementsurface.

Cover II is formed with the depending annular iiange I, which projectsinto the upper end of the casing and holds the cover from lateraldisplacement, and depending from the under side of the cover are theoppositelydisposed hooks or angular projections J,

Serial No. 592,046. (No model.)

which, when the cover is turned, engage the arms B and thus hold thecover from vertical displacement. The cover is formed with two openingsK on opposite sides of its center, which are adapted to be engaged byforked end L of the key M, and by this means the cover may be turned tolooking position or removed, as desired. The opposite end of the key isformed into a socket N for engaging the upper eXtremityD of the turningrod. A transverse bar or handle O is arranged midway the ends of the keyfor easily turning the same.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

l. The combination of the casing, the inwardly projecting arms, thebearing supported by the inner ends of the arms, the turning rod held inposition by the bearing, the casing-cover, and the oppositely-disposedangular projections depending from the casing and adapted to be turnedto position of engagement of the arms for locking the cover in place,substantially as shown and described.

2. The combination of the casing, the inwardly-disposed projections uponthe inner wall thereof, the turning stem inclosed by the casing, thecasing-cover, and the oppositelydisposed hooks depending from the underside of the cover and adapted to be turned beneath the inwardly-disposedprojections of the casing and thereby hold the cover in place,substantially as shown and described.

The combination of the casing, the inwardly-disposed arms or projectionsupon the inner wall thereof, the central bearing supported by the innerend of the arms entirely free from the said casing, the turning steminclosed by the casing, the casing-cover, and the oppositely disposedhooks depending from the under side of the cover and adapted to beturned into engagement with the said inwardly-extending arms between thecentral bearing and the inner wall of the casin g, substantially asshown and described.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL WEBB GARRISION.
